In addition to the famous impacts of atmospheric carbon on global warming, there is an equally worrisome effect of carbon dioxide on the oceans: ocean acidification (or OA for short). Here at I2SEA we have a series of resources about OA, including Our Acidifying Ocean, which is an introductory activity and virtual lab (note: now mobile compatible!).
A student suggested that we start a conversation topic about OA, and here it is! Have you heard about Ocean Acidification? If so, are you worried about it? How do you think we can best raise awareness about it among your fellow students and the general public? Have you seen particularly good links or films about OA that you would like to share? What are you doing to address the problem?

Save the ocean or die
Now more than ever we need to be aware of the impact of CO2 emissions on the entire terrestrial ecosystem. Even the ocean, the source of all life, is seriously affected. In fact, about 30% of the CO2 emitted dissolves in our oceans, causing chemical reactions that reduce the pH of seawater. This affects shell organisms and by domino effect the entire food chain. And who is at the top of the food chain: Man. Many nations are at the mercy of the oceans to survive, with economies based on fishing or tourism. Thus, the food security of these populations, as well as the biodiversity of many ecosystems are threatened by the acidification of the oceans. Let's be responsible, let's reduce our CO2 emissions.
